To vALI. WHoM P r MAY'coNcERN= Beit known that. I, C. WTHEODORE KRSCH, of Philadelphia, in the county of Philadelphia, in the State of Pennsylvania, have invented anew and improved Mode of Effecting the Coupling and Tightening of Belts orBands; and I do hereby declare that .the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specifi- Figure I is a side elevatipnot' my. combined belt-coupling and tightener, and

Figure II a top view of it. i v

The object of my invention is to effect the coupling of belts or bands, as well as the adjusting of the degree of tightness of belts or bands, by one and the same arrangement or machine.

To enable others skilled inthe artto understand my invention, I will describe its construction and operation.

TheA inclined wings A Aare connected at their narrow end by means of pin P, forming together-a hinge. The opposite ends of the wingsA A are provided with hooks o o o '0.` A screw, C, passes through the wings A A', the latter having (each of them) an opening, rv, for screw C to pass through. At each end of screwy C anut, S, is placed. l

' Havingdescribed its construction, I shall now describe its operation.

wings A'A. Screw C rests in the openings xV rv, which are seen in wings A A', and is to be so placed as to projectsuiciently over the wings A A for the action of the nuts S S. Now spread wings A A as far' apart as screw C may allow; then place or fasten the belt-ends to the hooks o o o o, and put the belt over the pulleys. If found, the belt being slack or better to slack for theavork to be done by the belt; then turn the nut or nuts S S toward the wings A A', which will cause the wings A A to come nearer together with their hook-ends, thereby effecting the tightening of the belt. i l

The belt has been out, also holes punched through it in corresponding distances with the hooks o o o o ofv In case wide belts or bands are used, then I place or fasten a corresponding number o'f the combined conpling and tigbtencr beside each other. In doing so, I am enabled to tighten one or the other side of the belt.

or the centre part of it, which hasnot been done yet by any-tightening-device in use.

The advantages arising of this invention are clearly seen. Having thus described my invention, what I claim. as new,'and desire to secure by Letters Patent, isl- An adjustable belt or band-clasp, (coupling) by means of which also the degree of tightness of a. belt or band can be eiected. y 2. A belt-clasp, combined with. belt-tightener, substantially in the manner as and forl the purpose set forth.
